If you want a swimming-ready audio device for switch, choose SilisoundTek Bone Conduction Swimming; if you need a speaker for listening under a pillow, choose Hesond Pillow Speaker Bone. The SilisoundTek is the more relevant pick for active use, with IP68 water protection and built-in 32GB music storage. Hesond is designed around hands-free listening in bed, where a wearable headset would be the wrong shape for the job.
These are not two versions of the same kind of headphone. One is an open-ear bone-conduction headset made for swimming and other movement; the other is a small sleep speaker intended to sit under a pillow. Neither product sheet provides evidence that either device is designed for a Nintendo Switch, so shoppers searching for the best lightweight wireless earbuds for switch, a low latency headphone for switch, or the best bluetooth headset for switch should be careful not to mistake general Bluetooth support for stated Switch compatibility or verified gaming latency.
• SilisoundTek’s biggest strength: IP68 waterproofing and 32GB onboard music storage make it purpose-built for listening while swimming. Trade-off: underwater playback requires MP3 mode, because Bluetooth cannot transmit underwater.
• Hesond’s biggest strength: it plays audio from beneath a pillow, without needing to wear earbuds or a headset. Trade-off: it is not water-resistant and is intended for sleep and music, not swimming.
• SilisoundTek fits: swimmers and active listeners who want a wearable, open-ear device and can use its stored music when away from a Bluetooth connection.
• Hesond fits: people who want bedtime or nap-time listening without putting anything on their ears, and who value its 30- and 60-minute sleep timers.
• For switch: neither sheet confirms Switch compatibility or provides a latency figure, so choose between them for their documented uses rather than assuming either is a gaming headset.
SilisoundTek makes the clearest case for swimmers. Its IP68 rating is the standout practical feature, and the built-in 32GB storage gives it a way to play music underwater. The important catch is the listening mode: Bluetooth does not work underwater, so the device needs to be switched to MP3 playback for swimming. That turns its storage from a secondary convenience into a central part of the swimming setup.
The headset uses bone conduction and sits on the ear rather than sealing the ears with in-ear earbuds. The product sheet also describes it as suitable for activities such as running, hiking, and skiing. Its Bluetooth 5.4 connection is listed with a range of up to 13 meters in the feature description, while another specification lists a 10-meter range. I would treat that as ordinary short-range wireless use, not a promise of a particular connection distance in every setting. It can pair with Bluetooth devices, but the sheet does not name the Switch or document gaming latency.
Battery life is listed as 8–10 hours of music or calls, with charging taking about 1.5 to 2 hours depending on which specification is used. That should interest someone who wants one wearable device for a workout or an extended day, though the listed runtime is not a guarantee for every volume level or playback mode. I’d skip it if the main goal is a speaker to leave under a pillow, or if you want a product with clearly stated Switch support and latency details. Its design and features point toward sport and swimming, not sleep or gaming.

Hesond takes a very different approach: it is a 6.1-inch bone-conduction speaker designed to sit under a pillow. You listen without wearing anything on your ears, which may be appealing if you dislike the sensation of earbuds or a headset while lying down. Its stated purpose is sleep and music, so it makes more sense for a bedtime routine or a nap than for movement, swimming, or gaming.
The battery is listed at 400mAh, with up to 20 hours of continuous operation and up to 12 days of standby. It also has timers that shut the device off after 30 or 60 minutes, a useful fit for someone who wants audio while drifting off without leaving it playing all night. But the product is explicitly not water-resistant. I would skip Hesond for swimming, outdoor workouts where water protection matters, or anyone looking for a conventional wearable Bluetooth headset. Its value is in its under-pillow format, not in trying to do everything.
• Best fit for swimming → SilisoundTek Bone Conduction Swimming. Its IP68 rating is the deciding feature. Hesond is not water-resistant.
• Best for underwater music → SilisoundTek Bone Conduction Swimming. Its 32GB built-in storage supports MP3 playback; switch to that mode because Bluetooth cannot transmit underwater.
• Best for listening under a pillow → Hesond Pillow Speaker Bone. It is designed to sit beneath the pillow and play without being worn on the ears.
• Best for avoiding earbuds at bedtime → Hesond Pillow Speaker Bone. It is a small speaker rather than an on-ear headset, and it includes 30- and 60-minute shutoff timers.
• Best for built-in music storage → SilisoundTek Bone Conduction Swimming. It has 32GB on board; Hesond requires a separately purchased Micro SD card for card playback.
• Best for a longer stated continuous runtime → Hesond Pillow Speaker Bone. Its sheet lists up to 20 hours, compared with 8–10 hours for SilisoundTek. Those figures are manufacturer-listed durations, not a direct test under identical conditions.
• Best for active, wearable listening → SilisoundTek Bone Conduction Swimming. Its features are directed toward swimming and other sports. Hesond is designed around staying in bed.
• Best documented choice for Switch gaming → neither. Neither product sheet confirms Switch compatibility or gives a measured latency figure. Bluetooth support alone does not settle either question.
For Switch shoppers, that last point matters more than a vague claim about Bluetooth connection quality. The word “wireless” does not tell you whether a headset will pair with your particular setup, and a stated Bluetooth version does not establish how much delay you will hear during gameplay. SilisoundTek is at least a wearable listening device, while Hesond is a pillow speaker; neither description makes either one a clear gaming pick.
The products also differ in what “hands-free” means. SilisoundTek is worn on the head, leaving the ears open while you move. Hesond avoids wearing a headset altogether, but it needs to be positioned beneath a pillow for its intended use. That distinction affects comfort and routine more than a comparison of Bluetooth versions would. A swimmer needs a device that stays with them in the water; a side sleeper is looking for something that can remain outside the ear.
It is also worth separating battery endurance from convenience. Hesond’s listed 20-hour runtime is longer than SilisoundTek’s stated 8–10 hours, but the two products are intended for different listening situations. SilisoundTek offers built-in storage and a faster stated charging window, while Hesond offers sleep timers and a pillow-based design. The more useful question is not simply which battery figure is larger; it is whether you need music during a swim or audio as you settle into bed.
My Verdict
I would choose SilisoundTek Bone Conduction Swimming if I wanted a wearable device for swimming, thanks to its IP68 rating and built-in 32GB storage for underwater MP3 playback. For switch, though, I would not buy either one without confirming compatibility and latency, because neither sheet supplies those details. Hesond is my pick only for the more specific job of listening under a pillow, where its sleep timers and non-wearable design make more sense. The right choice comes down to swimming versus sleep—not an unverified promise of Switch performance.
No. The product information says Bluetooth cannot transmit underwater. Use MP3 playback mode for swimming, with music stored on its built-in 32GB storage.
No. Its product information says it is not water-resistant. It is intended for sleep and music, so it is not the suitable choice for swimming or wet conditions.
Hesond lists up to 20 hours of continuous operation, while SilisoundTek lists 8–10 hours of music or calls. These are listed specifications, not results from a shared, controlled test.
Neither product sheet confirms Switch compatibility or provides a specific gaming-latency measurement. Bluetooth support alone does not confirm that either product will pair with your setup or feel responsive during play.
